I’m new here and hope I’m posting in the right forum. I am thinking about buying a PSP and have a few questions. Chances are the new ones will have the 2.50 firm ware and I want to now if these could be down graded. Is there a way to use a non psp memory because I don’t want to pay over a hundred for a gig. I want to use psp for watching movies and for the Genesis Emulator. Thanks in advance for the help
